Lines

100

When two lines cross these pairs of lines are called...

Intersecting lines

200

This special condition of intersecting lines occurs when two lines cross and create right angles.

Perpendicular lines

300

I begin at a point and then continue on forever in one direction. What am I?

A ray.

400

These pairs of lines will never intersect and are always the same distance apart. 

Parallel lines

500

When two lines intersect, what types of angles can be formed?

Right, acute, obtuse

Polygons

100

I have 5 sides and 5 vertices. What am I?

Pentagon

200

I have 10 sides and 10 vertices. What am I?

Decagon

300

I have 7 sides and 7 vertices. What am I?

Heptagon/Septagon

400

I am created when 8 different lines intersect, but not necessarily all at the same place. What type of polygon am I?

Octagon

500

I have curved lines and a gap between the edges of my shape. What am I?

Not a polygon

Transformations

100

I am the letter L but suddenly I am upside down and look like a 7. How was I transformed?

Rotation

200

I am a curly E but somehow now I look like a 3. How was I transformed?

Reflection

300

I am an N but now I look like a Z. How was I transformed?

Rotation

400

I am a K and I still look like a K but am about 6 inches to the left from where I began. How was I transformed?

Translation

500

I am a C but now I suddenly am a c. How was I transformed?

Dilation

Quadrilaterals

100

How can a square be classified?

Parallelogram, rectangle, rhombus, square

200

A 4 sided polygon that has only one set of parallel lines is called a...

Trapezoid

300

I have two pairs of congruent, parallel lines. What type of quadrilateral could I be?

Square, rectangle, parallelogram, rhombus

400

All of my sides are congruent. What can I be?

Square, rhombus

500

All of my angles are congruent. What can I be?

Square, rectangle

Angles

100

I can be found in squares and rectangles. I measure 90 degrees. I am created when two lines are perpendicular. What type of angle am I?

Right angle

200

We are created when two lines intersect but are not perpendicular. We can be found in triangles. What type of angles are we?

Acute angles

300

I measure more than 90 degrees. I can be found in a regular hexagon. I am created when two lines intersect but are not perpendicular. What type of angle am I?

Obtuse angle

400

I measure 180 degrees. I look like a straight line. I am formed when two rays head in exactly opposite directions. What type of angle am I?

Straight angle

500

I am created when two lines intersect or when two rays meet. What am I called in geometry?

An angle
